• At least one link connection is formed on the main body of the steering knuckle and thus easily enables the connection of a link such as a toe link or a steering linkage.
• the joint coupled to the drive shaft is designed as a joint joint.
• this joint is designed as a universal joint.
• Both types of joint allow the rotary movement of the drive shaft to be transmitted in a simple manner to the shaft journal that is non-rotatably connected to the vehicle wheel.
• a head of the shaft journal is positively connected to the head of the drive shaft or the joint and thus creates a non-rotatable connection between the shaft journal and the drive shaft or the joint.
• a head of the shaft journal is provided with a toothing which engages in a toothing of the head of the drive shaft or the joint.
• an outer shell of the constant velocity joint is at least partially accommodated in the joint receptacle.
